Objectives: The purpose of this study was to examine the use of dentifrice for children, the state of dentifrice for children on the market and the relationship between the bore of dentifrice and the amount of dentifrice used in an effort to provide parents, main consumers of dentifrice for children, with the right information on dentifrice. Methods: Data on the use of children`s dentifrice were gathered by investigating parents in Seoul and Gyeonggi Province in July and August, 2009. The selected parents had children aged one to five in Western age. Results: 1. As to the purchase of dentifrice for children, the largest group (75.9%) were aware of the name of the toothbrush used by their children, and the greatest group (97.3%) bought the toothbrush on behalf of them. Advertising was the most dominant source of information on the choice of dentifrice (51.8%), and non-professionals were the most common providers of information on that (55.9%). 2. The amount of dentifrice used at a time was a mean of 0.467±0.270 g. There was a wide disparity in that aspect from a low of 0.100 to 1.900 g. As to the influence of the size of the bore of dentifrice, the greatest amount of dentifrice was used (0.670±0.306 g) when the bore of dentifrice was 9 mm in size, and the bore size 9 mm was significantly different from the size 3 mm and 6 mm in that aspect (p<0.001). 3. There was one kind of imported dentifrice for children on the market. Concerning the fluoride ingredient of dentifrice, the biggest number of dentifrice contained MFP only. As to the size of the bore of dentifrice, there was a difference of 3 to 9 mm. Most of dentifrice for children included the pictures of particular characters. Conclusions: The above-mentioned findings illustrated that there is a serious concern for the intake of fluoride among infants and preschoolers, it`s needed to pay careful attention to the use of dentifrice. Dentifrice for children should be manufactured in consideration of the relationship between the size of the bore and the amount of dentifrice used.

Objectives : This study examined the stress-coping methods used by Dental Hygiene students according to their degree of self-leadership to provide basic data for students` self-leadership training programs. Methods : Dental Hygiene students in Seoul and Gyeonggi-do were surveyed to measure their self-leadership in six categories - self-expectation, rehearsal, goal-setting, self- compensation, self-criticism, and constructive thinking - and , in four categories - problem-centered coping, social support coping, emotional coping, and wishful thinking coping - on a scale of 1 through 5. Results : The findings of the study were as follows: The overall average score of self-leadership was 3.34 and the scores for each subfactor were 3.82 for self-compensation, 3.57 for self-expectation, 3.44 for rehearsal, 3.42 for goal-setting, 3.30 for self-criticism, and 3.12 for constructive thinking. The overall average score of stress-coping was 3.29 out of 5 and the scores for active coping were 3.14 for problem-centered coping and 3.38 for social support coping and for passive coping were 3.69 for wishful thinking coping and 2.95 for emotional coping. Self-leadership showed significant difference in terms of satisfaction with major and motivation for application. The six sub-factors of self-leadership and problem-centered coping and wishful thinking coping, the sub-factors of stress-coping, had significant correlations. Self-compensation and constructive thinking were significant factors of self-leadership that affect stress-coping. Conclusion : Based on the above findings, it was found that Dental Hygiene students` self-leadership is related to the use of efficient stress-coping. Therefore, it would be necessary to develop and apply educational approaches to improve their self-leadership so they can efficiently cope with various stressors that they will face after finding jobs.

Objectives: The purpose of the study was to investigate the appropriate management and implementation of the oral malodor prevention for the general people. Methods: A self-reported questionnaire was filled out by 420 subjects in Seoul and Gyeonggi Province from March to October, 2013. Except 19 copies, 401 copies were analyzed. The instrument of subjective oral malodor awareness and status was adapted from Yoon and Youn and partly modified. The questionnaire consisted of general characteristics(4 questions), oral malodor awareness(3 questions), oral malodor related characteristics(3 questions), self-diagnostic test of oral malodor(5 questions), and subjective oral malodor and health status(3 questions). Self-diagnostic test of oral malodor was score as yes(1 point) and no(0 point). The subjective oral malodor and health status scoring was done by Likert 5 scale. Cronbach alpha was 0.713 in the self-diagnostic test of oral malodor. Results: The self-recognition rate of oral malodor was 0.8%. When the level of oral malodor increased to 1 point, the self-test of oral malodor increased as the rate of 0.033(p<0.05). Conclusions: There existed no close correlation between subjective recognition of oral malodor and oral malodor self-test. Therefore, oral malodor should be measured by an expert counseling to make an accurate diagnosis. It is important to establish the appropriate oral malodor prevention program for the general people.

‘산·염기 적정’에 관한 웹 기반 시뮬레이션 학습 프로그램의 개발과 적용

전주연,우애자 이화여자대학교 교과교육연구소 2002 교과교육학연구 Vol.6 No.2

현재 교육 환경에서 과학 실험 경험의 부족으로 이해하기 어렵던 과학 지식은 웹 기반 시뮬레이션 가상 실험을 활용함으로써 실제와 유사한 실험 경험을 제공하고 빠른 학습 피드백으로 지식 이해도를 높일 수 있을 뿐만 아니라 학습자의 흥미와 학습 태도를 고조시킬 수 있다. 이 연구에서는 일반 화학 ‘산·염기 적정’ 단원에 대하여 웹 기반 시뮬레이션을 활용한 학습 집단(실험반)과 전통적인 강의 학습 집단(통제반) 사이에 학업 성취도의 차이와 웹 기반 시뮬레이션 학습에 대한 태도를 알아보았다. 웹 기반 시뮬레이션 학습 프로그램은 백영균(1999)의 ‘웹 기반 학습사태와 학습목표‘를 참고하여 개발하였다. 연구 결과에 의하면 실험반과 통제반의 학업 성취도는 수업 처치 전후에 실시한 검사에서 통계적으로 유의미한 차이는 없는 것으로 나타났다(p>.05). 웹 기반 시뮬레이션 수업에서 가상 실험 수행의 경험과 멀티미디어 요소에 의한 흥미 유발로 학습에 능동적으로 참여할 수 있다는 점에서 수업의 효과성, 수업 참여도, 학습 이해도 및 다른 강의에서 수업 방식 적용 여부에 관해서는 ‘대체로 그렇다’와 주위 집중의 부족과 개인차를 고려하지 않음으로 인해 수업 후 학습 의욕, 성적 향상 기대, 문제 해결에 대한 자신감에 관해서는 ‘보통이다’라고 응답한 학습자가 많았다. The purpose of this study is to investigate the effect of web based simulation instruction on the students’ scholastic achievement and learning attitude about acid-base titration in the general chemistry. We constructed the web based simulation program and two questionnaires. Tests were taken by 54 sophomore students (traditional lecture group : 27, web based simulation group : 27) before and after the class. The results of this study are as follows: There is no statistically significant difference in scholastic achievement between traditional lecture group and web based simulation group (p>.05). Each group shows statistically significant difference(p<.05) before and after the class. In terms of learning attitude toward the web based simulation instruction, students were satisfied with the effectiveness of the class, the class participation, the application of this technique to another classes, and etc. Based on the results of this study, a few suggestions can be made for web based simulation program to be organized and delivered properly. The level of achievement, learning styles, and cognitive modes of all students should be taken into consideration through activities to understand them in advance. Students' attention and concentration should also be considered by using appropriate multimedia elements.
